Chapter 44.3, Problem 1CC
Summary Introduction
To compare: The ways in which the
Concept introduction: The excretory system varies in the flatworm, earthworms and the insects. The earthworms have metanephridia, protonephridia in flatworms and Malpighian tubules in insects are present for excreting the metabolic wastes.

- Explain how insects are capable of secreting concentrated urine without depending on high blood pressure filtration.arrow_forwardThe bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.) By actively transporting ions out from the gills into the water? 3.) by excreting highly concentrated urine? 4.) by resorbing ions in nephronsarrow_forwardMatch the phylum with the excretory system. 1.
